UNDERWATER GOGGLES Filed Jan. 16, 1953 WVENTOR BY NEJVEE WQM ATTORNEY Patented Nov. 21, 1933 (Granted under the act of March 3, 1883, as amended April 30, 1928; 370 O. G. 757) This invention relates to underwater goggles and has for an object to provide a pair of goggles especially adapted for underwater use.

Another object of this invention is to provide Z a pair of underwater goggles adapted for use in j on while the wearer is in a medium of high pressure such asair and which will allow the pressure to gradually escape as it decreases after the wearer has entered a corresponding water pres. sure without allowing water to come in contact with the eyes.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts as will be described more fully'hereinaiter.

In the drawing:

Fig. 1 is a plan view of the underwater goggles constituting'this invention;

Fig. 2 is a section on line 2-2 of Fig. 1;

Fig. 3 is a section on line 33 of Fig. 1.

The goggles consist of an eyepiece holding skirt or apron l1 integrally connected to strap 12 and a buckle strap 13, the apron 11 and straps 12 and 13 being made of slightly elastic sheet rubber, and buckle 14 being constructed of non-corrosive metal or other non-corrosive material. The lens holders 15 for the lens 16 are molded as an integral part of the apron 11. Straps 12 and 13 are joined to the apron 11 by connecting wings 17. The vertical edges of the apron 11 are substantially thickened into ribs 18. These ribs 18 are substantially four times as thick as the strap or skirt, thereby making the edges somewhat stifier than the remaining portions. The Vertical ribs 18 continue up and across the back of wings 17 where they join a similar horizontal rib 19 across the top of the apron 11. Thus, there are ribs on three sides of the apron 11; the lower.

edge is quite flexible. By this method of constructions. seal is made across the forehead and at the temples of the wearer and the apron 11 below the lenses 16 is loose across the nose and cheeks. I I

The goggles are put on and adjusted to a snug fit while the wearer has his head above .water under'pressure in'a flooded submarine compartment, lock, or diving bell. As he rises through the water, expanding air in the goggles escapes around the bottom 20 of the skirt due to the seal across the forehead and at the temples provided by the ribs 18 and 19. The eyes are thus kept dry dur and vertical sides of said apron.

. It will be understood that the foregoing description and accompanying drawing comprehend only the general and preferred embodiment I of my invention, and that various changes may be made therein within the scope of the appended claims without sacrificing any of the advantages of the invention. 7

The herein described invention may be manufactured and used by or for the Government of the United States of America for governmental purposes without the payment of any royalty thereon.

I claim: I

1. Underwater goggles comprising an apron'of slightly elastic sheet rubber, means for securing said apron across the eyes of the wearer and means for sealing only the top and vertical edges of said apron above the eyes and against the forehead and temples of the wearer, said means comprising a thickened rib formed along the top 2. Underwater goggles comprising an apron of slightly elastic sheet rubber, means for securing said apron across the eyes of the wearer and means for sealing only the top and vertical edges of said apron against the forehead and temples of the wearer, and goggle lens holding means inherently molded in said apron. I

3. Underwater goggles comprising an apron of, slightly elastic sheet rubber, means for securing said apron across the eyes of the wearer and means for sealing only the top and vertical edges of said apron against the forehead and temples of the wearer, said securing means comprising a pair of strap means integrally projecting from the upper part of said apron and integral wing portions connecting said strap members and said apron adjacent its upper side.

4. Underwater goggles comprising an apron, goggle lens holding meansin said apron, means for securing said goggle apron across the forehead of the wearer, said underwater goggles being adapted to be placed in operative position while under pressure, means for sealing the top and vertical edges of said apron above the eyes and against the forehead and temples of the wearer,

[the lower edge of said apron below the eyes being ,free to-permit the escape of excess internal pres goggle apron across the forehead of the wearer, said underwater goggles being adapted to be placed in operative position while under pressure, means for sealing the top and vertical edges of said apron above the eyes and against the forehead and temples of the wearer, said sealing means comprising a thickened rib inherently formed along said top and vertical edges of said apron, the lower edge of said apron below the eyes being free to permit the escape of excess internal pressure as the external pressure is reduced.

6.
